COMMENT:raatri (night) is feminine, and candra (moon) is masculine. So the 4th line seems to speak of the combination of the feminine and masculine principles, or yin and yang, the passive and the active. This theme of masculine and feminine elements being joined together is picked up more conspicuously in the following verse.

EH Johnston:Had Nanda not gained Sundari or had she of the arched eyebrows not been united to him, the two of them would certainly have failed to reach the perfection of beauty, like the night and the moon if deprived of each other.

Linda Covill:If Nanda had not won her, Sundari, or if she, arch-browed, had withheld herself from him, then the pair would surely have appeared impaired, like the night and the moon without each other.
